Amazon, Nvidia, and AMD are jointly investing $310 million（約500億円） in Odyssey ML, an AI startup building world models that simulate the physical world in 3D—a technology the industry sees as the next frontier beyond language models.

What happened: Amazon, Nvidia, and AMD venture arms are investing $310 million（約500億円） in Odyssey ML, valuing the company at $1.45 billion（約2300億円）. The startup, founded by Oliver Cameron and Jeff Hawke (both from autonomous vehicles), builds world models—AI systems that simulate physics, dynamics, and spatial relationships rather than generating text. The 55-person team is based in London, Zurich, and Palo Alto.

Why it matters: World models represent a shift in how the industry thinks about AI progress. Language models alone cannot capture physics, body language, and dynamics—things Cameron says Odyssey's models understand. Influential AI researchers including Meta AI chief Yann LeCun, Google Deepmind CEO Demis Hassabis, and AI pioneer Fei-Fei Li have all publicly positioned world models as essential for advancing toward more capable AI systems. The backing from three major hardware makers and Google signals that this direction has become a priority for the industry.

What to watch: Odyssey uses AWS as its preferred cloud provider and runs on Amazon's Trainium chips, showing how the startup's architecture is already tied to one of its lead investors' infrastructure. Other backers include IQT (linked to the CIA), GV (formerly Google Ventures), and investor Elad Gil.
